Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 240 GDDR5 should in theory be a lot superior to the Radeon R7 M260 in general. (explain)

GeForce GT 240 GDDR5		54400 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 38400 (240%)

Texel Rate

The GeForce GT 240 GDDR5 is a small bit (approximately 3%) better at AF than the Radeon R7 M260. (explain)

GeForce GT 240 GDDR5		17600 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 440 (3%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 M260 is superior to the GeForce GT 240 GDDR5, and very much so. (explain)

Radeon R7 M260		5720 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 1320 (30%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
